Overview

The property is a basement conversion flat within a period terraced house. Although the flat appeared modern and well finished, the buyer instructed a Level 3 Building Survey to understand the true condition before committing.

The survey revealed a number of significant issues that were not visible during the viewing, particularly around dampness, drainage and the quality of the conversion works.

Key findings

  • Significant damp and moisture issues within the basement areas.
  • Poor quality workmanship in the basement conversion.
  • Inadequate ventilation and evidence of condensation.
  • Drainage and waterproofing concerns to below ground areas.
  • Further investigative works and repairs required.

Outcome

Armed with the findings, the buyer successfully renegotiated the price by £22,000 to reflect the cost of necessary repairs and improvements.

Without the survey, these hidden issues would likely have remained undiscovered until costly problems occurred.
